 ## Reward Design
 
 `RewardModel` is a Pydantic model with:
 
-- `value`
-- `components`
-- `rationale`
+- `value`: scalar reward for this step
+- `components`: dict of named sub-rewards
+- `rationale`: human-readable explanation
 
 Reward shaping is dense, not sparse:
 
-- positive reward for discovering required context
-- positive reward for correct intermediate decisions
+- positive reward for discovering required context keys
+- positive reward for correct intermediate decisions (priority, route, resolution)
 - positive reward for correct queue ranking progress
 - terminal reward from the deterministic grader score
 - penalties for invalid actions, redundant actions, and wasted steps

+## Baseline Scores
+
+### Rule-based baseline (no API key required)
+
+The deterministic rule-based baseline always takes the optimal action sequence and is used as a sanity check that the graders are correct and reachable:
+
+| Task                    | Score |
+|-------------------------|-------|
+| `easy_account_takeover` | 1.000 |
+| `medium_payout_hold`    | 1.000 |
+| `hard_queue_triage`     | 1.000 |
+| **average**             | **1.000** |
+
+### LLM baseline (GPT-4.1-mini)
+
+These are the reproducible scores from the OpenAI baseline runner. They demonstrate that the environment provides a genuine challenge to frontier models, particularly on the hard task:
 
-Programmatic graders live in [support_ops_env/graders](/home/batman/Downloads/presentation_template/support_ops_env/support_ops_env/graders).
+| Task                    | Score | Notes |
+|-------------------------|-------|-------|
+| `easy_account_takeover` | ~0.20 | Model skips mandatory set_priority / set_route / set_resolution before finalize |
+| `medium_payout_hold`    | ~0.35 | Correct context discovery but premature finalize |
+| `hard_queue_triage`     | ~0.13 | Multi-ticket ranking and per-ticket mandatory actions not completed |
+| **average**             | **~0.23** | |
+
+The gap between the rule baseline and the LLM baseline confirms the reward function produces genuine signal and the hard task challenges frontier models.
